1 Claim.

My invention relates to toys and more particularly to noise-making devices, and the principal object in view is to provide a device of this character for attachment to the rear axle of a. tricycle, or the like, and operation bya wheel of the tricycle to create a sound similar to that made by the engines of an automobile or tractor.

Another object is to provide a device of the character and for the purpose above set forth which is simple in construction, easy to apply, will not get out of order, and is inexpensive to manufacture.

To the accomplishment of the above, and subordinate objects presently appearing, the preferred embodiment of my invention has been illustrated in the accompanying drawings, set. forth in detail in the succeeding description, and

defined in the claim appended hereto.

In said drawings:

Figure 1 is a view in side elevation of a preferred embodiment of my invention applied,

Figure 2 is a view in top plan of the lower half of the casing, the vibratory blades, and the blade vibrating roller, drawn to an enlarged scale,

,Figure 3 is a view in longitudinal section,

Figure 4 is a view in top plan of the lower casing section,

Figure 5 is a view in end elevation, and

Figure 6 is a view in perspective of one of the hanger yokes.

Referring to the drawings by numerals, the illustrated embodiment of my invention comprises a cylindrical, elongated casing I including upper and lower semi-cylindrical sections 2, 3, having closed ends 4 and fittingtogether in opposed edge to edge, mating relation, to provide a sound chamber in said casing. Each section 2, 3 is provided with a pair of edge flanges 6 on the ends 4 thereof extending inwardly, the flanges of the sections mating in opposed pairs at opposite ends-of the casing. Each section 2, 3, is also provided with a pair of diametrically opposed, apertured lugs I extending laterally from the side edges thereof adjacent each end of the same, the lugs of one section mating flat with those of the other. Bolts 8 extended through mating lugs I and equipped with nuts v9 clamp said sections together in mating relation. The described casing I may be formed of any suitable material, preferably metal, adapted for amplifying sound.

A pair of vibratory blades, or reeds, III, of elongated rectangular form extend inwardly from the ends 4 of said sections into the chamber 5 in the axis of the casing I with inner ends spaced apart for a purpose presently seen. The outer ends of said blades III are fitted into countersunk seats II provided in the flanges 6 and ends 5 4 and are secured to the flanges 6 of the lower section 3 by screws 3' passing through said outer ends thereof and into said flanges 6. The blades l taper so that they are gradually reduced in thickness toward the inner ends thereof to facili- 1o tate vibration of the same, it being understood that said blades are formed of suitable resilient resonant metal.

A corrugated blade vibrating roller I2 is provided in the chamber intermediate the inner ends of the blades I0, said roller fitting endwise diametrically in the casing I, in the plane of said blades and being rotatably mounted by end trunnions |3 in suitable sockets I4 provided in the side edges of sections 2, 3. The corrugations of 5 the roller I2 form longitudinally extending radial ribs I5 thereon outwardly tapering transversely and designed under rotation of the roller to wipe past the inner ends of blades l0 and vibrate the same to create a noise simulating the sound of an automobile or tractor engine.

An elbow pipe section I6 depends from the bottom of the lower section 3 with its upper end opening into said chamber 5, said pipe section forming a sound outlet preventing mufiiing of the sound vibrations.

A grooved pulley I1 is fixed on one trunnion I3, e'xteriorly of the casing I, for driving said roller I2.

A pair of hanger yokes I8 of bar metal are provided for attaching the casing I to the rear axle I3 of the tricycle, represented at 20, adjacent one rear wheel 2| thereof, said yokes strad: dling the casing I, adjacent opposite ends thereof, and having flat to-p stretches 22 and legs 23 0) depending from said stretches and terminating in inturned apertured lugs 24 bolted to the lugs 'I of the upper section 2 by the before mentioned bolts 8. A plate 25 is extended across the axle 9 and bolted, as at 26, to the top stretches 22 of yokes I8, the arrangement being such that said plate and casing t clamp the axle I9 therebetween, whereby said casing is fixed to said axle to extend longitudinally crosswise thereof in underslung position with the pulley II adjacent the before mentioned rear wheel 2|.

A grooved drive pulley 21 is rotatably mounted on the axle I9 and suitably attached to the wheel 2| to be rotated thereby. A belt 28 operatively connects the pulley 21 to thepulley I1.

The operation of the device, together with the construction thereof, will be readily understood from the foregoing without further explanation.

Manifestly the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the subjoined claim.

What I claim is:

A device of the class described comprising an elongated cylindrical casing closed at both ends and forming a sound chamber therein, said casing including a pair of semi-cylindrical sections mating edge-to-edge and detachably secured together, a pair of vibratory blades in said casing disposed in the axis thereof and having outer ends clamped between the ends of said sections and inner ends spaced apart upon opposite sides of the diametrical center of the casing, a blade vibrating roller in said casing intermediate said spaced apart ends of the blades rotatably mounted at its opposite ends in opposite sides of said casing, respectively, and having longitudinal ribs thereon for wiping engagement under rotation of the roller with said inner ends of said blades to vibrate the same, means for rotating said roller, and'means to attach said casing to a relatively fixed object comprising a pair of bails eX- tending laterally from said cylinder, and a plate detachably secured to said bails.
